Replacing the Battery in a Back-UPS Pro

What is the proper procedure for replacing the battery for the Back-UPS Pro 280, 420 and 650 VA Models

Product Line:

Back-UPS Pro 280, 420 and 650 VA

Environment:

BP280PNP, BP280S(C)
BP420PNP, BP420S(C)
BP650PNP, BP650S(C)

Cause:

Self Test

The UPS performs a self-test automatically when turned on, and every two weeks thereafter. During the self-test, the UPS briefly operates the loads on-battery. If the UPS passes the self-test, it returns to on-line operation.
If the UPS fails the self test it immediately returns to on-line operation and lights the replace battery LED. The loads are not affected. Recharge the battery overnight and perform the self-test again. If the replace battery LED lights again, refer to the battery replacement instructions below.
